Actress Sarah Greene has revealed that in the space of just two years, she has gone from portraying teenagers to the mothers of teenagers.

The Cork woman (33) is known for her roles in shows like Penny Dreadful and Rebellion and admitted there are parts she would have played not so long ago she could no longer now audition for.

“There’s different age brackets. I can no longer play parts I played two years ago,” she said.

“I was playing 17-year-olds and now I’m playing the mothers of 17-year-olds. It’s just part of my job I suppose.”

The Dublin Oldschool star said she doesn’t spend much time dwelling on projects once she’s finished them.

“The minute you finish a job, you let it go. You don’t sit around going ‘this is going to make me’. You do the job and then concentrate on the next character,” she said.

“It’s like any job, you just switch off. I don’t have a lot of problems doing it.”

Sarah, who trained at The Gaiety School of Acting, currently lives in London with her family and has found it easier to get work at home since she left.

“I live with my family, so that’s nice. Sometimes you have to go away to get work here,” she told the Herald.

“Since I moved to London I’ve got so much work.

“I don’t work in London that much except for theatre.

“It’s a completely different medium. I got to do two shows last year and adored it.”

Despite her success in the film business, Sarah isn’t shy about revealing an acting career sometimes means you can go months without a steady income.

“If you want to do this job you have to give yourself over to the fact that you’re going to be unemployed,” she said.

“Two years ago, I had five months off. You just have to go, ‘OK, what’s for me won’t pass me by’. You have to be prepared to be unemployed.”
